FERNANDEZ, Constantino et al. Kidney transplantation from HLA-incompatible live donors: Efficiency and outcome of 32 patients after desensitisation. Nefrología (Madr.) [online]. 2017, vol.37, n.6, pp.638-645. ISSN 1989-2284.

Desensitisation is a procedure undergone by the recipient of a kidney transplant from a donor who is cross-match positive. The aim of this study was to present the outcomes from our hospital of kidney transplant recipients from HLA-incompatible live donors after desensitisation.

We studied 32 patients aged 46 ± 14 years with a mean fluorescence intensity (MFI) versus class I HLA of 7979 ± 4089 and 6825 ± 4182 MFI versus class II and relative intensity scale (RIS) of 8.9 ± 7.6. The complement-dependent cytotoxicity (CDC) cross-matching test was positive in 18 patients, flow cytometry was positive in 7 patients and donor-specific antibodies (DEA) were detected in 7. The protocol used was rituximab, plasmapheresis/immunoadsorption, immunoglobulins, tacrolimus, mycophenolic acid derivatives and prednisone.

After 8 ± 3 sessions of plasmapheresis/immunoadsorption, 23 patients were trasplanted (71.9%) and desensitisation was ineffective in 9. There were baseline differences in MFI class I (P < .001), RIS (P = .008), and CDC cross-matching, DSA and flow cytometry (P = .05). MFI class I and RIS were predictors of inefficiency in ROC curves. After follow-up of 43 ± 30 months, 13 patients (56%) presented postoperative bleeding, 3 (13%) delayed graft function, 4 (17.4%) acute rejection, 6 (26%) CMV viraemia and 1 (4%) BK viraemia. Five-year patient survival was 90%, with 86% allograft survival. Five-year creatinine was 1.5 ± 0.4 and proteinuria was 0.5 ± 0.7.


Kidney transplantation from HLA-incompatible live donors after desensitisation was possible in 71.9% of patients. MFI class I and RIS predict the inefficiency of desensitisation. Five-year allograft survival (86%) was acceptable with a low incidence of acute rejection (17.4%), although with a greater trend towards postoperative bleeding.
